Abstract

The invention discloses a miniaturized multipath optical fiber rotary connector, which comprises a core part, wherein the core part comprises a rotary end wire outlet assembly, a fixed end wire outletassembly, a transmission mechanism and a prism assembly, wherein the rotary end wire outlet assembly and the fixed end wire outlet assembly are installed at the two ends of the transmission mechanismrespectively; the transmission mechanism comprises an inner shaft; and the prism assembly is installed in the inner shaft of the transmission mechanism. The prism assembly comprises a special-shapedDove prism and a prism sleeve, wherein the special-shaped Dove prism is installed in the prism sleeve. The special-shaped Dove prism comprises an incident surface and an emergent surface which are opposite to each other at the two sides; extension lines of the incident surface and the emergent surface form an included angle of 90 degrees; the bottom between the incident surface and the emergent surface is a horizontal refracting surface; the upper side of the refracting surface is a cylindrical non-working surface; the incident surface and the emergent surface of light at the two sides are working surfaces; and the light enters from the incident surface at one side and exits from the emergent surface at the other opposite side after being refracted by the refracting surface at the bottom;and the cylindrical non-working surface of the special-shaped Dove prism, the prism sleeve and the inner shaft are coaxial.

Description

technical field [0001] The invention belongs to the field of optical signal transmission, in particular to a miniaturized multi-channel optical fiber rotary connector. Background technique [0002] Fiber Optic Rotary Joint (FORJ: Fiber Optic Rotary Joint), also known as fiber optic slip ring, fiber optic rotary joint, optical hinge, etc., is used to solve the problem of optical signal transmission between relative rotating parts, that is, to ensure that the transmission of optical signal And interrupt. Compared with traditional electrical connectors, optical fiber rotary connectors have the following advantages: use light for signal transmission, no electromagnetic leakage, good confidentiality, anti-electromagnetic interference; non-contact transmission, no wear, long life, up to 5 million revolutions . Frictionless, it can be used in flammable and explosive environments; the transmission bandwidth is much larger than that of electrical connectors, and when used in conjun...
